通过这一款选修课小系统，学生可以登入学生端进行选课及其他的操作，管理者通过登入管理端可以进行对选修课系统的数据的管理和维护。在学生端主要设置了3个基本功能：学生选课、学生情况、选课情况等；在管理端主要设置了9个基本功能：增加/删除学生、增加/删除课程、更改学分、填写成绩、学生情况、选课情况、保存数据等。这些功能基本上能满足选课的基本要求。此程序可以初步体现课程设计的目标。-An optional academic course or subject.

本分布式小区智能网络模型采用符合现场总线(Fieldbus)要求 的CAN技术，以带CAN总线端口的主控机和单元控制器CAN端接口构成的 CAN网络层，下层为由带RS485端口的住户采集器和单元控制器RS485端 接口构成了RS485网络层，向上则利用PC机连接CAN网络层，作为智能 化小区管理中心，从而基本实现智能小区管理、控制、报警、信息采 集和自我检测的功能。 本文从智能小区、现场总线、CAN技术到“CAN+RS485”双底层网 络模型的软、硬件研究，较为详细的介绍了其设计、调试运行和期间 各种问题的解决。 -The Distributed Intelligent Network model district in line with Fieldbus (Fieldbus) requirements CAN technologies to bring CAN bus port主控机and cell controller CAN-side interface consisting of CAN network layer, the lower the grounds with RS485 port Household acquisition and cell controller interface RS485 client constitutes a RS485 network layer, up modem to connect to the PC using the CAN network layer, as the Intelligent Community Management Center in order to realize the basic intelligent community management, control, alarm, information collection and self-testing function. This article from the Intelligent Community, Fieldbus, CAN technology to

This circuit automatically turns on a night lamp when bedroom light is switched off. The lamp remains ‘on’ until the light sensor senses daylight in the morning. A super-bright white LED is used as the night lamp. It gives bright and cool light in the room. When the sensor detects the daylight in the morning, a melodious morning alarm sounds. The
